Cities and Biodiversity Outlook (CBO)

The Cities and Biodiversity Outlook (CBO) is a global assessment of the links between urbanisation, biodiversity, and ecosystem services. Drawing on contributions from more than 120 scientists and policy-makers from around the world, it summarizes how urbanisation affects biodiversity and ecosystem services and presents 10 key messages for strengthening conservation and sustainable use of natural resources in an urban context. A summary can be found in CBO – Action and Policy, and additional detail in CBO – Scientific Analysis and Assessment.
